As is typically the case in the spring for the rising seniors, the 2012 Rivals150 has undergone an overhaul. Significant changes include a new No. 1 player and a couple of significant jumps into the five-star range.

In a class that is lacking a true superstar, the unique qualities of Isaiah Austin have landed him in the top spot of the rankings. He came so close to grabbing the No. 1 ranking after the summer, but the concerns about his inconsistent production and tendency to float on the perimeter kept him out of that top spot. Those concerns still exist, but the development of Austin's game has made those concerns less of an issue looking to the future.

There is simply no prospect with Austin's ability to impact a game. His combination of length, skill and feel for the game is freakish.

Right behind Austin is the top perimeter prospect in the country, Shabazz Muhammad. A tough competitor and consistent producer, Muhammad continues to make strides as a perimeter shooter.

No. 3 Andre Drummond lost his hold on the No. 1 spot, but he is still one of the top post prospects in a class that is loaded with quality big men.

And at No. 4 is the most unique perimeter prospect in the country, Kyle Anderson. At 6-foot-8, Anderson can control a game from the point guard position.

The top rising prospect in the country, Mitch McGary, takes the No. 5 spot and is followed by another high riser of the spring, Devonta Pollard. McGary jumped all the way from No. 92 to No. 5, while Pollard went from No. 29 to No. 6.

Rodney Purvis holds down the No. 7 spot in his first ranking with the 2012 class.

At No. 8 is Jarnell Stokes, who has been one of the top big men and top producers in the spring.
